What is density? student definition
Answer:
Density is the degree of consistency
Explanation:
volume x mass = density
Answer:
Density can be defined as the mass per unit volume of a substance.
Explanation:
Density is simply the mass per unit volume of a substance. When you are finding the density of the substance;
You first need to know the volume of a substance and the mass of that substance.

Which of the following best describes a tissue?
Group of answer choices
A group of organs that all have similar functions.
A group of similar cells that serve the same purpose
A random collection of cells.
A singe cell that has a specific function.
Answer:
I would say b
Explanation:
it would be b because tissues that are similar form one organ but a group of organs is a system so its b.
The best statement that describes a tissue is - A group of similar cells that serve the same purpose.
In multicellular organisms, tissue is a cellular organizational level that is present between similar cells and a complete organ. It is a group of cells that have a similar structure and function.
The space between cells in tissue is filled with a nonliving material, the intercellular matrix that varies from tissue to tissue in amount.Various tissues then undergo organization to form organs. Cells are the most basic part of an organizationtissues make muscles that help in movementThus, "A group of similar cells that serve the same purpose" is best describes tissue.

What difference do you see between ribose and deoxyribose sugars?
What is RNA ?
What is replication?
Answer:
ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.
Explanatioim smart now give brainliest plz
Answer:
Ribose, found in RNA, is a "normal" sugar, with one oxygen atom attached to each carbon atom. Deoxyribose, found in DNA, is a modified sugar, lacking one oxygen atom (hence the name "deoxy"). In ribose, carbon atom #2 carries one hydroxyl group (colored red).
RNA is a ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule.Explanation:

Write about an experience, either real or imaginary using these words chemical energy, electric energy, kinetic energy, mechanical energy, nuclear energy, potential energy, radiant energy, seismic energy, sound energy, and thermal energy
Answer:
I stopped to think for a moment, and realized chemical energy is found in food. Then, I thought about how the other day when I saw lightning, that is an example of electric energy. Then I thought about how when throw a ball, that is a form of kinetic energy. The other day, when I was hammering a nail into a piece of wood, that was a form of mechanical energy. An example of nuclear energy would be the nuclear power plant by our house. Before my book fell off my table, this is an example of potential energy. The energy from the sun is an example of radiant energy. Volcanoes and earthquakes around the world are an example of seismic energy. Sound energy would be the balloon that I popped the other day. Thermal energy would be the heat I feel from the heater.

Grassland songbirds often nest in the same grassland-wetland complexes as waterfowl, particularly in a certain part of those complexes, namely, upland habitats surrounding wetlands. Although some wildlife management procedures directed at waterfowl, such as habitat enhancement or restoration, may also benefit songbirds, the impact of others, especially the control of waterfowl predators, remains difficult to predict. For example, most predators of waterfowl nests prey opportunistically on songbird nests, and removing these predators could directly increase songbird nesting success. Alternatively, small mammals such as mice and ground squirrels are important in the diet of many waterfowl-nest predators and can themselves be important predators of songbird nest. Thus, removing waterfowl-nest predators could affect songbird nesting success through subsequent increases in small-mammal populations.
In 1995 and 1996, researchers trapped and removed certain waterfowl-nest predators, primarily raccoons and striped skunks, then observed subsequent survival rates for songbird nests. Surprisingly, they observed no significant effect on songbird nesting success. This may be due to several factors. Neither raccoons nor striped skunks consume ground squirrels, which are important predators of songbird nests. Thus, their removal may not have led to significant increases in populations of smaller predators. Additionally, both raccoons and striped skunks prefer wetlands and spend little time in upland habitats; removing these species may not have increased the nesting success of songbirds in the uplands enough to allow detection.
According to the passage, which of the following is true about the role played by ground squirrels in the ecology of grassland-wetland complexes?
(A) While not important in the diet of raccoons or striped skunks, ground squirrels are a significant source of food for other waterfowl-nest predators.
(B) Whereas ground squirrels are typically important as predators of songbird nests, their opportunistic predation on waterfowl nests also has an observable effect on waterfowl nesting success.
(C) Although most waterfowl-nest predators prey on small mammals such as mice and ground squirrels, populations of ground squirrels tend to increase quickly enough to compensate for this level of predation.
(D) Although ground squirrels have been known to prey on songbird nests, a larger portion of their diets is usually provided by predation on waterfowl nests.
(E) Since larger predators tend to prefer small mammals to songbird eggs as a food source, a large population of ground squirrels plays an important role in controlling opportunistic predation on songbird nests.
Answer:
(A) While not important in the diet of raccoons or striped skunks, ground squirrels are a significant source of food for other waterfowl-nest predators.
Explanation:
According to the passage, some predators of waterfowl nests prey opportunistically on songbird nests. Therefore, some wildlife management procedures directed at waterfowl, such as habitat enhancement or restoration, may also benefit songbirds. However, some procedures such as predator control may not always lead to benefits for the songbirds. For example, some predators of waterfowl nests such as raccoon and striped skunks are not predators of small mammals such as mice and ground squirrels who themselves are predators of songbird nests. So removing the striped skunk and raccoons from the habitat of the waterfowl and songbird nests, may not bring any benefit whatsoever to the songbirds. However, many other predators of waterfowl nests are also predators of squirrels and mice.

Which chemical is released by (2) WBC's that produces a non-specific inflammatory response?
Answer:
cytokines
Explanation:
Non-specific immune responses are integral to host cellular defense mechanisms. It is a general response, mediated by white blood cells, where cells rapidly react to pathogenic infiltration.
Here receptors on cells recognise molecules shared by a broad spectrum of pathogens, or even react to signals from damaged, injured or stressed cells like inflammatory cytokines in a cytokine storm.

Liquid and gases can take the shape of their contains.
Liquids have not fixed shape and they readily flow.
Gases are random and they occupy the contains they fill .
Volume is the amount of space occupied by a substance. Gases can take up any amount of space in a container. Liquids can readily flow and take up spaces too. Solids are fixed and have a definite volume.
